General Foster telegraphed that he had received reliable information of the re-enforcement of Longstreet by one division of Ewell's corps, and the advance of the combined forces by the direct road on Knoxville. General Parke was ordered to send all trains to Knoxville, and to prepare to fall back on that place with his whole force should the enemy advance. General Parke has no information of an advance upon this place this morning. General Spears,w ho is on the Knoxville and Rutledge road at Flat Creek, reported a rumor yesterday that the enemy's cavalry was crossing in force at Dyer's ferry. This has ot been confirmed. General Foster has a report that Morgan is advancing from Dalton in command of cavalry. This place will be held until the enemy threatens seriously, when we will fall back upon Knoxville.

The general commanding desires you to take every precaution to guard trains, and you will keep open the courier-line as long as possible with this place and with Knoxville should this line be interrupted.

Very respectfully, your obedient servant,

SAM'L WRIGHT,

Assistant Adjutant-General.
